Overview

Watt+Volt is a Greek energy services company headquartered in Athens. Established in 2011 as WATT AND VOLT S.A., it entered the market after receiving authorization to supply and trade electricity. The company developed beyond conventional retail energy supply by combining electricity and natural-gas sales with digital customer services, energy-management tools, energy-efficiency services, electric-vehicle charging, renewable-energy support, and participation in European energy-innovation projects. Its early development focused on building the infrastructure and digital capabilities needed to operate in a liberalizing energy market. In 2012, Watt+Volt installed smart meters through an innovation-support framework and created an online partners platform for electricity-supply applications. Electricity-trading activity began in 2013. The company then introduced MyWatt, an electronic bill-management service, in 2014 and expanded its regional presence through subsidiaries in Bulgaria and Serbia. A mobile version of MyWatt for iOS and Android followed in 2015, alongside the creation of an energy-services company and the acquisition of a stake in the Bulgarian Watt+Volt EMT venture. Watt+Volt broadened its commercial scope in the second half of the 2010s. It obtained a natural-gas supply license in 2015 and began natural-gas supply operations in 2018. Its retail network expanded across Greece, reaching 15 stores in 2018, 35 in 2019, and 60 in 2020. The company also introduced electronic billing, online customer management, gas-boiler installation, boiler and heat-pump maintenance, net-metering services, and electric-vehicle charging infrastructure. In 2018 it installed its first charging stations, and in 2020 it launched the Chargespot application for locating or using charging services. The company has pursued regional and wholesale-market participation as well as retail growth. In 2016 it became active in the European Energy Exchange, described in the reference material as the first Greek private company to participate there. It later entered the Hungarian power-exchange market and began trading European Union emission allowances. Subsidiaries or group entities were established in Bulgaria, Serbia, North Macedonia, and Albania, supporting the group's regional energy-trading and supply activities. Digital self-service is central to the Watt+Volt proposition. MyWatt enables customers to review consumption, examine historical usage trends, manage electricity and gas accounts, and make payments. Later upgrades added additional account functions, gas-supply management, biometric or PIN-based quick login, and fully digital contracting. In 2021, the company promoted an end-to-end electronic contract process that allowed customers to conclude an electricity-supply agreement online without visiting a physical location. Watt+Volt has also participated in European research and innovation programs, including enCOMPASS, inteGRIDy, HEAT4COOL, HORIZON 2020, BRIGHT, and PRECEPT. The company coordinated PRECEPT and reported strong outreach results from enCOMPASS. Its activities indicate a positioning that combines energy retail with technology-enabled consumption management, distributed-energy services, sustainability, and electrified mobility. The available reference material does not provide current ownership, financial results, senior executive names, or a confirmed corporate website, so those fields remain unspecified.

History

Watt+Volt was established in Greece in 2011 under the name WATT AND VOLT S.A. after receiving a license for electricity supply and trading. Its initial development coincided with the opening of the Greek energy market to greater private-sector participation. In 2012, the company invested in smart-meter installations intended to provide real-time visibility into energy consumption and created an online Partners platform for processing electricity-supply applications. It commenced electricity-trading operations in 2013. The company added digital customer tools and regional operations during the following period. MyWatt was launched in 2014 as an electronic means of managing electricity bills, and a Bulgarian subsidiary was established in the same year. In 2015, MyWatt became available as a mobile application for iOS and Android. Watt+Volt also established an energy-services company, created a Serbian subsidiary, received a natural-gas supply license, and acquired a 50 percent interest in the Bulgarian Watt+Volt EMT venture formed with the CE group. Wholesale-market and innovation activities became increasingly important from 2016 onward. Watt+Volt registered with the European Energy Exchange and participated in European projects including encompass and Horizon 2020's inteGRIDy program. The London Stock Exchange subsequently recognized the company among its 1,000 Companies to Inspire Europe. In 2017, Watt+Volt began opening branded stores across Greece, creating a physical retail presence alongside its digital channels. In 2018, the company launched natural-gas supply operations, introduced electronic bill delivery, installed its first electric-vehicle charging stations, and developed an e-learning platform. Its Greek store network reached 15 locations. MyWatt was upgraded with additional web functionality. During 2019, the group expanded into North Macedonia, entered the Hungarian power-exchange market, exceeded 100,000 supply customers, and began trading European Union emission allowances through the European Energy Exchange. It also introduced net metering, expanded to 35 Greek stores, strengthened electronic call-center services, and added gas-boiler installation. Watt+Volt continued regional and technology expansion in 2020. It established an Albanian trading subsidiary, received authorization to operate as a renewable-energy aggregator, and launched Chargespot for electric-vehicle charging. The company reported operating 60 Greek stores and added digitally signed contracts, gas-account management through MyWatt, and boiler and heat-pump maintenance. Its European engagement included coordination of the PRECEPT project and participation in BRIGHT, while the company's work in enCOMPASS was described as achieving particularly strong outreach results. The COVID-19 lockdown period prompted the Menoumespiti customer-support initiative, which offered a discount to Watt+Volt customers and supported the Shedia organization. In 2021, the company introduced an end-to-end online electricity contract and enhanced MyWatt with quick login using biometric authentication or a four-digit PIN. The available material documents Watt+Volt through this phase of expansion but does not establish its present ownership, leadership, financial scale, or later corporate developments.
